An electric release fastening device for a thin-profile space has a fingerprint identifier, a micro drive motor, a change gear set, an electric controller, an electric battery, a moveable fastening cassette, a fastening cassette control unit and a locking locator. When the fingerprint identifier reads the correct identification information, the micro drive motor is ordered by the electric controller to drive the change gear set, and then change the position of the fastening cassette control unit. This switches the positioning or release state between the moveable fastening cassette and the locking locator, and controls or electrically releases the product cover. With this configuration, the electric release fastening device can be assembled into thin-profile spaces with improved applicability.

1. Field of the Invention
The present invention relates generally to a fastening device, and more particularly to an innovative one which is configured into an electric release type mounted into a thin-profile space.
2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 37 CFR 1.98.
The fastening device is widely applied to the “open/close” structure of various products, enabling users to control the positioning or release state of the product enclosure.
A conventional fastening device is generally configured with a mechanical drive control mode, allowing the user to position and release the fastening device via a preset operating mode (e.g.: pressing, pushing and rotating). That is to say, such fastening devices lack a locking function. Yet, the existing fastening device is combined with several types of locking devices such as a number lock. However, such a combined structure has a shortcoming of bigger space, making it difficult to adapt to thin-profile products.
With the development of products towards lightweight and compactness, there is a huge demand for a combined electric fastening device, but an important technical concern is how to develop a thin-profile structure for the applications.
Thus, to overcome the aforementioned problems of the prior art, it would be an advancement if the art to provide an improved structure that can significantly improve the efficacy.
Therefore, the inventor has provided the present invention of practicability after deliberate experimentation and evaluation based on years of experience in the production and development of related products.
The enhanced efficacy of the present invention is as follows:
Based on the unique configuration of the present invention wherein the “electric release fastening device for thin-profile space” mainly comprises a fingerprint identifier, a micro drive motor, a change gear set, an electric controller, an electric battery, a moveable fastening cassette, a fastening cassette control unit and a locking locator, the electric release fastening device can be assembled into thin-profile space for a wider range of applications with improved applicability.

Based on the structural configuration wherein the casing is provided with a cover jacking member at exterior of the moveable fastening cassette, the cover can be pushed open under release state, enabling users to open it more easily.
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
A micro drive motor 30 is mounted into the thin-profile space 13 as a driving source. The micro drive motor 30 is provided with an output screw 31.
A change gear set 40 is mounted into the thin-profile space 13. The change gear set 40 includes a start gear 41, an end gear 42 and a plurality of change gears 43 defined between the start gear 41 and end gear 42. Of which, the start gear 41 is meshed and driven by the output screw 31 of the micro drive motor 30, and a driving portion 44 is protruded from one side of the end gear 42.
An electric controller 50 is mounted into the thin-profile space 13, which includes a circuit board 51, a processor 52 and an electric control component 53.
